Inger, it looks like the field with the extra text is the Approver's comments field. Is that correct? I'm assuming that the field is getting populated as part of the workflow. Are you able to see where in the workflow that field is getting updated? That would be the first place you'd need to look to see why this is happening. A screen shot of the workflow and the action updating this field would help the community to be able to respond.

I think Enrico Knapp nailed it. Having never been privy enough myself to be in a place where Lazy approvals were utilized, I did not know this would happen. Another thought, if you really want to have the approver comments displayed on the list without all the extra Jargon, would be to see if you could format the approval comments from the Lazy approval and store them in another field that you display. It looks like the approver comments are the very first line, and you could probably use a RegEx to extract those and save those to another field for display.
